Cobweb Spider discovered by Mardon (#1544)

Sighting Info

This spider was inside of a curled up leaf on an apple tree. When I unwrapped the leaves I found what looks to me to be three different species of yellow spiders. They were all the same size and all had woven silk balls with them that they seemed to be guarding. Note in one picture you can see a brown ball being excreted by the spider. Is this his digestive waste? The excreted brown ball can also be seen on the leaf in one photo.
